Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress

Global Change Biology, Volume 32, Issue 1, January 2026.
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Ontogenetic shifts in wood anatomy and leaf traits in tropical dry forests

New Phytologist, Volume 249, Issue 2, Page 848-859, January 2026.
Summary Trees experience changes in environmental conditions and biophysical constraints as they grow that may lead to shifts in functional traits. While ontogenetic shifts in leaf traits are relatively well understood, changes in wood anatomy traits from seedlings to adults are less clear, especially in tropical dry forests where drought strongly ...

Fluctuations in tissue growth portray homeostasis as a critical state and long-time non-Markovian cell proliferation as Markovian

Royal Society Open Science, 2023
Tissue growth is an emerging phenomenon that results from the cell-level interplay between proliferation and apoptosis, which is crucial during embryonic development, tissue regeneration, as well as in pathological conditions such as cancer.

Amazonia's Cassava and Manioc Through Historical Times

The Journal of Latin American and Caribbean Anthropology, Volume 30, Issue 4, December 2025.
ABSTRACT This provocation calls readers to think more deeply about the role anthropology could play in radically disrupting plant blindness. Thanks to Environmental Humanities, the natural world is no longer apprehended as a mere backdrop to human activity.

Incorporating sub-universes to address the issue of chagas in different educational contexts [PDF]

, 2013
Although Chagas has been traditionally addressed just from a biomedical point of view, due to its multiple factors and the diverse actors involved, it is necessary to consider it as a really complex problem characterized by four large dimensions ...

Impact of C18 Epimerization of Indole‐ and Pyrazole‐Fused 18β‐Glycyrrhetinic Acid Derivatives on PTP1B and TCPTP Inhibitory Activity: Synthesis, In Vitro, and In Silico Studies

ChemMedChem, Volume 20, Issue 22, November 18, 2025.
The indole derivative (FC‐114) and the N‐phenylpyrazole (FC‐122) of glycyrrhetinic acid are both potent inhibitors of the Protein Tyrosine Phosphatase 1B, with IC50 values of 0.48 μM and 1.15 μM, respectively. However, their activity decreases by up to four times when the 18β‐H position is epimerized to 18α‐H or when the carbonyl group at the C11 ...

Functional generalism in plant–hummingbird interactions: Causes and consequences from a plant perspective

Functional Ecology, Volume 39, Issue 11, Page 3339-3350, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant species pollinated by animals differ in the pool of visitors they attract. Some attract functionally similar animals, while others engage with a broader set of functionally distinct visitors; we term this species‐level variation functional generalism.
